Goal

Detect when a Tailscale posture integration has been modified or removed from a tailnet.

Strategy

This rule monitors Tailscale logs for posture integration changes where @target.type is TAILNET and @target.property is POSTURE_INTEGRATION. It triggers on both REMOVE and UPDATE events. Posture integrations enforce device compliance requirements such as disk encryption and OS version. Removing or modifying these integrations could allow non-compliant devices to connect to the tailnet.

Triage and response

  • Investigate the user {{@usr.name}} that modified or removed the posture integration.
  • Identify which posture integration was changed and assess the impact on device compliance requirements.
  • Review other recent changes to tailnet security settings by the same user for a pattern of policy weakening.
  • If the activity is not expected, begin your organization’s incident response process and investigate.
